This unit covers introductory concepts of mixtures and solutions. Students think about how mixtures and solutions, and atoms and molecules can influence new technologies developed by engineers. The first lesson explores the fundamentals...

Do you know the difference between a mixture and a solution? Test your knowledge in the junkyard as you try to dissolve various objects in water. Requires Shockwave.

Demonstrates, step-by-step and with examples, how to set up and solve 'mixture' word problems.

Learn the definitions of a solution, solute, and solvent. Understand how molarity is used to quantify the concentration of solute, and comcalculations related to molarity.

Explore all about chemical mixtures on this site including solutions, alloys, suspensions, colloids, dissolving, examples, and facts.

This Chem4kids tutorial teaches the basic properties of solutions.

Students investigate the property dependence between concentrations and boiling point. First, they investigate the boiling point of various liquid solutions. Then they analyze data collected from the entire class to generate two boiling...

A laboratory experiment where students classify matter into a homogenous mixture, heterogeneous mixture, solution, or pure substance. Also students will test for physical and chemical changes.

Resource contains and example problem and solution of how to compute percent compound within a mixture when given the mixture's mass and element percents.

Students will be able to describe elements and compounds, and explain how mixtures differ from compounds.

[Free Registration/Login may be required to access all resource tools.] In this lesson, students expand their study of mixtures to show that solids and gases can also act as solvents. Additionally, they take a look at situations in which...

To increase students' awareness of possible invisible pollutants in drinking water sources, students perform an exciting lab requiring them to think about how solutions and mixtures exist even in unsuspecting places such as ink. They use...

During this lab students will experiment to see whether a salt and vinegar solution can clean a tarnished penny. Included on site is lesson plan and student worksheet.

Students investigate the property dependence between concentrations and boiling point. In Section 1, students first investigate the boiling point of various liquid solutions. In Section 2 they analyze data collected from the entire class...

Experiment shows students how to use the lowered freezing point of water to chill another mixture (ice cream) to the solid state. Teacher's notes provide background information.

In this lab, students will demonstrate observation skills as they design an experiment to separate colors of various water-based pens in order to learn about mixtures and solutions. Students will determine a variable to test and complete...

Explains what the Tyndall Effect is and uses a diagram to model its impact on two different mixtures. Includes causes, examples, a look at suspensions and solutions, and an experiment to try.

In this chemistry lab, learners investigate whether water molecules have any space between them by filling a glass with water, and adding salt without the water overflowing. They will also experiment with the temperature of the water.

This lesson will explain the properties of a suspension, and describe why it is unique from other mixtures. It is 2 of 2 in the series titled "Suspensions."

A collection of video lectures from a general chemistry course taught at the University of California, Berkeley. The course teaches periodic table, chemical bonds, molecular shape, phase changes, chemical reactions, stoichiometry,...

[Free Registration/Login Required] This flipchart provides a multitude of hands-on activities for identifying, arranging and creating sentence maps for various water and aqueous systems.

This is a complete course in chemical stoichiometry, set in a scenario that shows how stoichiometry calculations are used in real-world situations. This course has been designed to not only help you strengthen your skills with...

Students conduct an experiment to determine how varying the composition of a construction material affects its strength. They make several adobe bricks with differing percentages of sand, soil, fibrous material and water. They test the...

"Matter is everything." So begins this comprehensive website on the physical and chemical properties of matter in its four main states: solids, liquids, gases, and plasmas. The text is large and easy-to-read. Students will enjoy the...
